Performance Optimization
Core Web Vitals Improvement
Google's Core Web Vitals, LCP, INP, CLS, directly influence rankings and ad quality scores. Systematic improvement attacks each metric's real causes (slow origins, JS bloat, layout instability) with field-data verification, not lab-score theater.
Key points
- Measure field data (CrUX/RUM) alongside lab tests; field data is what ranks.
- Fix LCP with faster TTFB, priority hero assets, and preloaded fonts.
- Fix INP by deferring JS, breaking long tasks, and trimming third parties.
- Fix CLS with sized media, reserved ad slots, and stable font rendering.
- Optimize specifically for mid-tier mobile, that's the ranking baseline.
- Validate fixes in the field over 28-day windows, not single lab runs.
- Keep third-party scripts on a budget with documented owners.
- Recheck after every theme, plugin, or ad-stack change.
Field note
Trust field data over lab scores for every decision that matters. Lab tests run one device on one network; your visitors bring hundreds of combinations, and rankings follow them.
Frequently asked questions
Do Core Web Vitals really affect rankings?

What scores should we target?
'Good' thresholds on all three for 75%+ of real visits, not just homepage lab tests.
Why do lab and field scores differ?

Field data aggregates over ~28 days, improvements appear gradually, then stick.
